oups , j´ai vu que le gars a posté comment il faisait:
Blimey, thanks for all the great feedback... I think this thread has gone off course now!
Anyway, much appreciated. I´ve posted a few images to sort of explain how things are done.
1. The background photo is taken.
2. The light probe is photographed at multiple exposures to capture all the levels of light in the area.
3. It´s then tranformed into a panorama, which is later wrapped around the 3D scene as a global light source ( using the multiple levels of light which are stored into a HDR file.)
4. A photo is taken of the probe with the same angle of the final shot, which you later use in the 3D software to line the reflective sphere up with a digital one ( effectively rotating the lighting into place)
5. Different layers are posed/prepared in the 3D software before the final rendering is done.
6. Each layer is rendered using the lighting captured with the reflective sphere, and then composited in Photoshop.
--->il n´a utilisé photoshop qu´a la fin, pour superposer les images du travail qu´il a fait avec d´autres logiciel.
